Styles may Vary - This third-party accessory for the Super Nintendo games console allows you to play US Super NES and Japanese Famicom games cartridges on a European Super Nintendo. It works by having two cartridge ports: you insert a PAL cartridge into port A and the import cartridge into port B. The adaptor passes the region-lock signals to the PAL cartridge and all other signals to the NTSC cartridge, thereby fooling the console into thinking it is a domestic game.
